[Resolved] Pass $_POST Data To iframe

[jwbrown77]

Hello,

I have a somewhat rare situation. I am attempting to pass $_POST data from a textarea field on a form into a iframe.

I have a page, say test.php. This page has access to $POST['message']. $POST['message'] contains newlines and other special characters.

From test.php, I am attempting to call an iframe. With normal data, the link for the iframe is usually ok if I just send it as $_GET values. e.g.:

<iframe src=\"testiframe.php?id=$_POST['id']\">

But since $POST['message'] contains newlines, the newlines can't be carried over into the $GET value. I have tried it both straight and with urlencode, neither with any luck. The text works, but newlines do not.

Does anyone know an eloquant solution to this? I was considering writing the contents of $_POST['message'] to a temp text file, then calling the contents of that temp file from the iframe page and erasing it. But that seems extravagant.

Has anyone ever tried passing data from one page into an iframe using anything other than $_GET values? Any help would be appreciated.

Thanks.

Off the top of my head give this a shot:

<form name="form1" method="post" action="whatever.php" target="iframe1">

<iframe src = "..." id="iframe1" name="iframe1">

(I always use both name="" and id="" to appease the various browsers ... if I recall IE loves 'name' more than 'id' and every other browser could care less about 'name')

Another solution is if the message isn't too terribly large then you can pass it as a $_GET variable by base64_encode()'ing the text ... that reduces it to alphanumberic characters (newlines and all)

In my never ending quest to use the easiest solution, I decided to try the base64_encode/decode solution and it worked like a charm. 🙂

Thanks a ton, now I don't have to rig up some complex form or javascript solution.

I will flag this thread as solved. Thanks again.
